VEHICLE-TIRE.

Specification of Letters Patent.

Application filed April 4, 1919. Serial No. 287,476.

To all whom it may concern:

Be it known that we, JEAN AUcUsTE PRINCE and ALBERT LOUISGILLEs,-citizens of the Republic of France, both residing at 16 RuedAngleterre, Nice, Alpes-Maritimes, France, have invented new and usefulImprovements in and Relating to Vehicle-Tires, of which the following isa specification.

The object of the present invention is to construct an elastic tirewhich, while being capable of being adapted to all kinds of vehicles,allows the air-tube to be dispensed with.

The characteristic feature of this tire re sides in the fact that itcomprises as novel element a particular arrangement of metallic springwhich gives the tire the necessary elasticity.

The invention is also characterized by a particular method of mountingthe tread, constructed as described, on the rim of the wheel.

The accompanying drawing shows, but

merely by way of example and in no way limitatively, a tire constructedaccording to the invention.

Figure 1 is a vertical section of the tire mounted on a wheel.

Fig. 2 is a view of the development of one of the springs.

Fig. 3 is a View of'the wheel as a whole.

a designates the tread, of rubber combined with cloth, leather or anyother suitable and usual material, in which is or are sunk the spring orsprings b, of which the development is shown in Fig. 2. Each of thesesprings consists of a steel band, of desired I width, in which areformed slots 6 in such a manner as to leave strips 12 which form theelastic portions proper of the spring. These springs, the number ofwhich is determined by the resistance which the tire is required topresent according to the weight and the nature of the vehicle, areeither single or superposed in such a manner as to form series which areplaced side by side in the tread a. The marginal portions of thesesprings are solid instead of being perforated. These springs are bent insuch a manner as to adopt the form of a tire as shown in Fig. 1, whenthey are sunk in the said tread.

They could also be made either in one piece cut fnom a sheet of metal orthey could be made in several pieces fastened together.

The tread can be given any desired. form, but that shown in the drawingis preferred.

It is mounted on the usual rim 0 having a cheek (Z which is attached bymeans of bolts 6.

The mounting of each bolt e presents a pcculiar feature in so far as itis fixed to the rim 0 by a collar 0 which renders the bolt solid withthe wheel. through the-marginal portions of the springs b and over it isslipped a sleeve 7" which plays the part of a stay and holds the treadin place on the rim.

' If desired, metal washers 9 can be sunk inv The said bolt passesItwill be understood that the springs need not be sunk in the material,but could be sim ply placed against the inner wall thereof.

In other words, the'tread would be mounted freely upon them. i

, Finally the elasticity of the springs will be' calculated bv thedesigner according to the loads to be carried by the vehicles providedwith this type of tire.

Claim:

A vehicle tire comprising, in combination,

a tread, elastic members sunk in the material 7 of said tread, boltspermanently fixed to. the wheel and-passing through the tread andtheelastic members, sleeves on said bolts serving as stays between theedges of the elastic members and washers for holding said sleeves inposition.
